METHOD AND APPARATUS FOR METAL ARTIFACT REDUCTION IN THREE-DIMENSIONAL X-RAY IMAGE REPRODUCTION BY USING ARTIFACT SPACE INFORMATION

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus just about image reproduction, and in more details, to reduce a metal artifact in the image reproduction by using artifact space information.;SOLUTION: At least one uncalibrated image (for example, an X-ray image and a perspective image) is collected (400 and 514), the uncalibrated image is calibrated (412 and 516), and the calibrated perspective image is formed. Receiver-transmitter conversion is calculated by using at least one calibrated image (414 and 518). A reproduced space is formed by using at least the receiver-transmitter conversion (416 and 520). At least one calibrated perspective image and at least two of the receiver-transmitter conversion and the reproduced space are synthesized (418 and 524), and at least one display image can be formed. This image can be shown (420 and 526) by using display devices (218 and 318).;COPYRIGHT: (C)2006,JPO&NCIPI
